VII/A Patented May 24, 1932 UNITED STATES ROBERT FINDLAY GRAHAM, OFLONDON, ENGLAND APPARATUS FOR PASTEURIZING- BEER OR OTHER LIQUIDS.Application filed December 9, 1930 Serial No. 501,112, and in GreatBritain September 5, 1930.

This invention relates to apparatus for V pasteurizing beer or otherliquids by the method in which a sealed container with the liquidtherein is submitted to a stream or spray of heated pasteurizing liquid.

The invention is a modification of an apparatus for pasteurizing beerand other liquids by the method described above compris v ing a platformor carrier for the liquid containers, a guide of spiral form to engagethe containers and cause them to move across the carrier on relativemovement of the carrier and guide and means to direct streams or a sprayof pasteurizingliquid on to the containers, the carrier being preferablyrotatable and the guide fixed'so that the carrier makes a number ofrevolutions during the movement of the containers across it.

The present invention comprises apparatus of the kind described forpasteurizing beer or other liquids wherein the guide to engage thecontainers and cause them to move across the carrier on relativemovement of the carrier and guide is a cam or member of comparativelyshort length extending at an angle from the edge of the carrier. 7

Preferably the guide or cam is of such length and at such an angle thata container while in engagement with it is caused to move across thecarrier a distance equal to the diameter of the container.

According to a further feature of the invention means are provided tocause the gulde or cam to traverse across the carrier. One form ofapparatus according to the present invention will now be described withreference to the accompanying drawings wherein Fig. 1 shows a plan Viewwith parts broken away, a I

Referring to Fig. 3, two concentric rings of standards 1, 2are connectedat the top" and towards the bottom by radial members. 5. A platform orcarrier 3 of ring form is supported at its edges on rollers 4L, 5carried on the standards. The framework of the platform carries on itsunderside'a rack '6 by which it is connected through a pinion 7 mountedon a shaft8, and gearing 9, 10, 11 (see Fig. 1) to a driving motor 12.The platform or carrier is constructed of parallel sided metal radialplates 13 carried on the framework'(see Figs. 5 and 6).. Between eachpair of plates there is thus a tapering space in which is placed atapering radial member 14 of such a width as to leave narrow slots 15between itsedges and the adjacent edges of the plates 13. ,Said taperingradial members 14 have their sides bent downwards as shown at 14a inFig. 6 sothat they stand at a slightly higher-level than the plates 13and constitute means to bear against the liquid containers. Thecontainers are indicated at 16 and the plates 13 are of a width correspending to the diameter thereof.

A guide or cam 17 of comparatively short length extends close to thecarrier 3 at an angle from the edge of the carrier as shown in Fig. 5.Said guide or cam is cast integral with and extends from the lower endof a Vertical stem 18 which at its upper end at 19 is of rectangular boxform with its side faces flat to act as bearing surfaces and slide in abox shaped guide 20 extendingacross the carrier. The box shaped guideis'bolted at .its upper end to the top structural members 21, 22extendinground the apparatus. A screw 23 carried in hearings in the endsof the box shaped guide 20 extends across the top thereof and engages athreaded hole in a member 24 bolted to the box form top 19 of the stem18. The box guide 20 is extended upwards to form a container for thescrew 23 and is closed by a removable cover 25. I One end of the screwis squared at 26 to receive an operating handle and the other end isconnected through gearing 27; 28 and a vertical shaft 29 to a star wheel30 which 9 projects into the path of a pin carried on the carrier. 31indicates clutch mechanism.

The guide or cam 17 is disposed with its one end adjacent the point atwhich the bottles are fed to .the carrier 3 and it is of such a lengthand at such an angle that a container while in engagement with it iscaused to move across the carrier 3 a distance equal to the diameter ofthe container.

' A series of shallowtrays32 are supported on the framework so as toextend completely heater and 38 a high temperature heater for round theinner edge of the apparatus.

the pasteurizing fluid. The heater 37 is connected by a pipe 39 to apipe 40 extending The pipe 40 perforated pipes 42 extendingover'thecompartment 36 and to branch pipes 43 extending over thecompartments 33. In the form of the invention illustrated thecompartments 33 and 34 are connected and may be considered as a singlecompartment. The heater 38 is connected by a pipe 44 to a pipe 45extending round the outer edge of'the apparatus and said. pipe 45' isconnected by branches 46 to perforated pipes 47 extending over theintermediate compartment 35. Suitable controllingvalves are provided inthe several pipes. I 1

By this arrangement low temperature pasteurizing fluid is suppliedto thecompart- V ments 33, 34 and 36 and high temperature fluid to thecompartment 35. It will be understood, however, that other arrangementsof piping and mixing valves may be provided whereby fluid f any desiredtemperature may be supplied to compartments which may be greater innumber than those illustrated. V

Concentric drainage tanks 48, 49 and 50 are arranged under the carrier 3and are supported on the framework of the The two outer tanks 48 and 50are connected together by pipes 51. 52 is an outlet pipe for the liquidfrom the tanks 48 and 50 and which is connected by the pipe 53 with thelow temperature heater 37 54 is a similar outlet pipe from theintermediate tank 49 vided to deliver the liquid containers 16 to thecarrier 3 at the feeding point and automatic apparatus may also beprovided to receive the containers from the point'56 (see Fig. It willbe understood, however, that the delivery of the containers to and fromI the carrier may be by hand.

and which is connected by the pipe .55 with In operation a container 16is fed to the platform 3 at the .point'57 (see Fig. 5) and is carriedround thereby. After a complete revolution the guide or cam 17 causes itto move across the carrier 3 a distanceequal i el pasteurizing partments33, 7 through the perforated bottoms ofthe trays The liquid suppliedthrough the compartments 33 and 34 may be at a temperature of say to F.During the next severalrevolutions they are submitted to liquid at ahigher temperature supplied to the compartment 35 at say 140 F. 'Duringthe latter part of their travel they are submitted againtocoolerliquidat-100 to110 F. supplied through'the compartment 36. Thepasteurizing liquid passes through the spaces 15 between the taperedmembers 14 andthe radial plates 13 to the collecting tanks 48, 49. and50in which it is collected and from whichit is returned to the heatingapparatus 37 and 38.

then carried round for a complete 7 reach the point- 56 atwhich they areremoved. During the first part of their trav- 7 liquid is supplied tothe com- 34, 35 and 36,-and-passing 7 WVhen it is desired to remove .allthe con-i tainers from the apparatus the guide is moved across'thecarrier by means of the screw 23 at the upper end of thestem 18. Thus itmay be hand operated from the end 26 'or' the clutch mechanism maybe puting position whereby the cam-17 is moved in a step by step manner fromthe star wheel 30. Though'the guide or cam 17 is shown at the inner edgeofthe platform'or' carrier it will be understood that-it may be at theouter edge when the containers will- 7 be fed to the platform at theouter edge andremoved at "the inner edge.
